CALEB A. LIBBY, OF EVANSVILLE, WISCONSIN, ASSIGNOR OF ONE-HALF TO MARTINV. PRATT, OF SAME PLACE.

SPRING-BED.

SPEOIFIGATION forming part of Letters Patent No. 234,303, dated November9, 1880,

Application filed April 29, 1880. (ModeL) To all whom ct may concern Beit known that I, CALEB ANoIL LIBBY, a citizen of the United States,residing at Evansville, in the county of Rock and State of Wisconsin,have invented a new and useful Improvement in Spring-Beds, of which thefollowing is a specification.

The object of my invention is to furnish a cheap, durable, easy,wood-spring bed, which may be raised at the head, also easily reversed,thereby keeping it in the best possible shape. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figure1 is a surface view of the entire bed. Fig. 2 is a side view, showingone side spring, the bolster, and the manner of raising and lowering thehead of the bed. Fig. 3 is an end View, showing one end spring, bolster,and slide on end of slats.

Similar letters refer to similar parts throughout the several views.

In the drawings, A is a cross-piece at what is termed the head of thebed. B is a similar cross-piece at the foot of the bed. The ends of saidcross-pieces rest on the sides of the bedstead, thereby supporting theentire bed in the bedstead.

O is a slat running lengthwise in the center of the bed, fastened on theunder side of crosspieces A B at the points a a.

D is a spring running horizontal, with crosspieces A B on the under sideof the same, fastened in the center at the points a a. Both ends aresimilarly constructed in this respect.

E E are side springs running lengthwise of the bed, resting on the endsof the end springs, D D, at the points I) b.

F F and G G are a series of slats, which may be increased or diminishedin number and length to accommodate different -sized bedsteads, slitlengthwise or not, as preferred. The ends 0 c are secured in place bythe crosspieces H H. The entire series is kept in place on thecross-piece B by the pins 01 d, and may be taken up and reversed alltogether. The ends a e of this series of slats are kept in place andallowed to spring independently by means of a slide constructed asfollows:

Two cross-pieces, I I, are fastened at the ends to slats F F, havingblocks f f between the slats. This slide can be moved to differentpoints by removing the fastenings and then sliding the piece I to orfrom the end of the slats and securing it at the changed position, thusaltering the spring of said series of slats at pleasure.

J is a cross-piece running either over or under the slat U, with itsends resting on the side springs, E E, at the points 9 g, and, beingmovable, can be used to change the spring of the bed.

K is what is termed the bolster, on which rests one end of the slats F FG G.

L L are standards passing loosely through cross-piece J, the upper endsbeing secured to the bolster K. Holes are formed in the stamiards,through which are passed pins, which can be removed from one set ofholes and passed through another, thereby adjusting the bolster higheror lower, as desired. If desired, the pins of one standard only may bechanged, thereby raising or lowering one side only, and consequentlymaking one side higher than the other.

Having thus described my invention and mode of operating it, I claim asnew therein and my invention 1. In a bed-bottom, the side springs, E,perforated near the bolster K, as shown, combined with the verticallyand horizontally adjustable bolster K, side slats, F, and intermediateslats G, admitting of longitudinal play, as set forth, substantially asand for the purposes described.

2. In a bed-bottom, the side springs, E, and end springs, D, incombination with side slats, F, secured to strips H and I, intermediateslats G, secured at one end to strip H and allowed a free longitudinalbut a limited lateral play at the other end in the strip I, andvertically-adjustable bolster K, substantially as and for the purposeset forth.
